How to delete that rows, when i get text from URL? - ios

Question

i try to get some text from an URL and put it out in a UITextView.
Thats my code in the ViewController:
NSString *urlString = #"http:/...";
NSError *error = nil;
NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString] options:kNilOptions error:&error];
if (error)
NSLog(#"%s: dataWithContentsOfURL error: %#", __FUNCTION__, error);
else
{
NSString *result = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];
NSLog(#"%s: result = %#", __FUNCTION__, result);
// if you were updating a label with an `IBOutlet` called `resultLabel`, you'd do something like:
self.mytextview.text = result;
}
Now the simulator shows that text in my view:
Sorry, the text is german :)
Now how can I hide or delete that html, head, body etc.?

Answer 1

It displays like this because you are downloading the content of that PHP file which is in HTML format.
You can create a method to find & delete each HTML tag between "<" and ">"
- (NSString*)stringByRemovingHTMLtags:(NSString*)string {
NSRange range;
while ((range = [string rangeOfString:#"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
string = [string stringByReplacingCharactersInRange:range withString:#""];
return string;
}
Then set your text in the UITextView like this:
self.mytextview.text = [self stringByRemovingHTMLtags:result];
EDIT: In order to get the content of the <p> tag use this method:
- (NSString*)getPtagContentFromString:(NSString*)htmlString {
NSRange startRange = [htmlString rangeOfString:#"<p>"];
if (startRange.location != NSNotFound) {
NSRange targetRange;
targetRange.location = startRange.location + startRange.length;
targetRange.length = [htmlString length] - targetRange.location;
NSRange endRange = [htmlString rangeOfString:#"</p>" options:0 range:targetRange];
if (endRange.location != NSNotFound) {
targetRange.length = endRange.location - targetRange.location;
return [htmlString substringWithRange:targetRange];
}
}
return nil;
}
Then set your text in the UITextView like this:
self.mytextview.text = [self getPtagContentFromString:result];

You should use UIWebView and load your html text like this:
[_webView loadHTMLString:result baseURL:nil];
